Classic Blender keymap mouse behavior -> Industry Compatible keymap [Change MMB to LMB]
You can manually edit the way the view port works by going to

Edit &gt; Preferences &gt; Keymap &gt; 3D View &gt; 3D View (Global) &gt; Rotate View


Click the box in the third column and hit the preferred mouse interaction, e.g. just middle mouse button.

For me the biggest annoyance was that I wasn't able to rotate my view (orbit) using Alt + middle mouse button, because of some obscure settings in my OS (Linux Mint / Ubuntu). Therefore I didn't need to change all mouse interaction settings and could just selectively choose some view port interactions to change manually; perhaps the same holds for you. Hope this helps.
